Spreadsheets Across the Curriculum module/Geology of National Parks course. Students calculate an answer from a bathymetric map by summing volumes of vertical prisms.

Pennies have a monetary face value of one cent, but they are made of material that has a market value that is usually different. It is the value of the materials that requires attention in this problem. While it is interesting to compare the face value with the value of the materials, this does not have any bearing on the calculations. Interference between these two notions of value is a possible area of difficulty for some students.

Students follow weather forecasts to gauge their accuracy and produce a weather report for the class. They develop skills of observation, recording and reporting.

The purpose of this study was to examine the comparative influence of college administrator credential programs, on-the-job experiences, and the ISLLC Standards in the development of leadership expertise among urban public school principals. An exploratory, ex-post-facto research design used both quantitative and qualitative approaches. A survey of 101 randomly selected urban school principals from 25 of America’s largest metropolitan school districts was given, followed by telephone interviews with a subset of 20 randomly selected survey participants. Data were analyzed through the use of inferential and descriptive statistics and descriptive narratives. On-the-job experiences were significantly more important in developing leadership expertise than college credential programs on each of 41 ISLLC-based learning tasks. However, college credential programs are also important sources of leadership development. Several significant differences were found between comparative ratings of learning tasks by subgroups (experience, gender, school type). Respondents ranked 78% of the ISLLC Standards as very important to the field of school leadership. Interview subjects expressed concern about lack of preparation in budgeting, data analysis, teacher evaluation, and change management.

Spreadsheets Across the Curriculum module. Students build a spreadshet to calculate grams solute to add to liters solvent to produce solution of desired concentration (mol/L).

Kindergartners measure each other's height using large building blocks, then visit a 2nd and a 4th grade class to measure those students. They can also measure adults in the school community. Results are displayed in age-appropriate bar graphs (paper cut-outs of miniature building blocks glued on paper to form a bar graph) comparing the different age groups. The activities that comprise this lesson help students develop the concepts and vocabulary to describe, in a non-ambiguous way, how height changes as children get older. The introduction to graphing provides an important foundation for both creating and interpreting graphs in future years.

As written, this problem gives students all of the information they need to estimate the thickness of a soda can.

his is a version of ''How thick is a soda can I'' which allows students to work independently and think about how they can determine how thick a soda can is. The teacher should explain clearly that the goal of this task is to come up with an ''indirect'' means of assessing how thick the can is, that is directly measuring its thickness is not allowed.

This is an activity where students learn about inquiry by designing an experiment on bean plants with the goal of growing the tallest plant. Students work in groups to plan the growing conditions of the control and three experimental plants. Students collect data for about three weeks and analyze their data to see if their hypothesis is correct or not. The end product can be a report presented in a number of ways.

This activity is a center investigation where students learn about wind force using a fan/wind tunnel and objects.

SSAC Physical Volcanology module. Students build a spreadsheet to calculate velocity of rising magma in steady-state Plinian eruptions using conservation of mass and momentum.

In this kinesthetic activity, the concept of energy budget is strengthened as students conduct three simulations using play money as units of energy, and students serve as parts of a planetary radiation balance model. Students will determine the energy budget of a planet by manipulating gas concentrations, energy inputs and outputs in the system in this lesson that supports the study of climate on Mars, Mercury, Venus and Earth. The lesson supports understanding of the real-world problem of contemporary climate change. The resource includes a teacher's guide and several student worksheets. This is the second of four activities in the lesson, How do Atmospheres affect planetary temperatures?, within Earth Climate Course: What Determines a Planet's Climate? The resource aims to help students to develop an understanding of our environment as a system of human and natural processes that result in changes that occur over various space and time scales.

The purpose of this task is to continue a crucial strand of algebraic reasoning begun at the middle school level (e.g, 6.EE.5). By asking students to reason about solutions without explicily solving them, we get at the heart of understanding what an equation is and what it means for a number to be a solution to an equation. The equations are intentionally very simple; the point of the task is not to test technique in solving equations, but to encourage students to reason about them.

This task can be used as a quick assessment to see if students can make sense of a graph in the context of a real world situation. Students also have to pay attention to the scale on the vertical axis to find the correct match.

These problems are meant to be a progression which require more sophisticated understandings of the meaning of fractions as students progress through them.

This task provides a context for performing division of a whole number by a unit fraction. This problem is a "How many groups?'' example of division.

In this video segment adapted from NOVA, follow novice runners as they train for a marathon, and discover how quickly the body responds to regular aerobic exercise.

Searching for things on the Internet can be like hunting for a needle in a large haystack. Just how large is the Internet?

Students set up and run the experiments they designed in the Population Growth in Yeasts associated lesson, using simple yeast-molasses cultures in test tubes. Population growth is indicated by the amount of respiration occurring in the cultures, which in turn is indicated by the growth of carbon dioxide bubbles trapped within the culture tubes. Using this method, students test for a variety of environmental influences, such as temperature, food supply and pH.
